1 LPCXpresso55S36 overview
The LPCXpresso55S36 board is a powerful and flexible, evaluation and development
platform for NXP LPC5536 microcontroller (MCU). It belongs to the LPCXpresso family of
boards — boards for NXP LPC MCUs based on Arm Cortex-M cores.
The board is compatible with the Arduino UNO R3 and Mikroe click boards. It can be
used with a wide range of development tools, including NXP MCUXpresso IDE, Keil
µVision, and IAR Embedded Workbench. The board is lead-free and RoHS-compliant.
For debugging the LPC5536 MCU, the LPCXpresso55S36 board uses an onboard
debug probe, known as MCU-Link OB (OB stands for "onboard"), which is based on
another MCU, LPC55S69. For simplicity, MCU-Link OB is referred to as "MCU-Link
debug probe" or just "MCU-Link" and the LPC5536 MCU is referred to as "target MCU" in
this document.
This document provides details about the LPCXpresso55S36 board interfaces, power
supplies, clocks, push buttons, jumpers, and LEDs.
